Pleeeeease answer this question... and if u know more... could you answer the above too? its a 30 mark homework.. that question is 5 marks..

1)Glucose Homeostasis
2)Enzymes involved in various metabolic process work optimally at a certain temperature, if the temperature changes they would not work as efficiciently. human life is only compatible with a narrow range of temperatures. Core temperature changes of the order of 3°C will not interfere with physiological functions, but any variation outside that range has very serious effects. For example, at 28°C, the muscles can no longer respond, at 30°C, confusion occurs and the body can no longer control its temperature, at 33°C, loss of consciousness occurs, at 42°C, the CNS breaks down with irreversible brain damage, and at 44°C, death occurs, the result of the body proteins starting to denature.
3)Sweating leads to formation of water on the skin, as the water is EVAPORATED, the process of the evaporation cools you down.
4)water, urea, dissolved ions, creatanine
5) The release of glucagon from the pancreas increases blood glucose. or more simply it normally increases after a meal.
